To all whom it may concern: tion of my governor secured to a balance- Beit known that I, GEORGE G. ANNABLE, wheel.

45 vier;T of a balance-Wheel provided with my Connected to the connection F at g is a 95 governor. Fig. is a like View to Fig. l, with spring G, the opposite extremity ot which is the governor in a diierent position from that preferably supported by an eye g', secured to illustrated in Fig. l. Fig. 3 is a vertical secthe wheel A. This spring is of suiiicient tional view taken on line w fr, Fig. l; and strength to overcome the centrifugal force of 5o Fig. t is a face View of a modified constructhe Weight until a certain revolution of the 10o seeks the center by reason of the action of the spring' G. As soon as theincreased steam admitted by the inward position of the weight E causes the Wheel to revolve more quickly, the weight is then forced outward by centrifugal force.

As the weight is arranged upon a guide, it will be understood that there is but one motion thereof-t-hat is, from the center outward, or vice versa. Accordingly, the operation of said weight is very quick, and the governor is thus rendered extremely sensitive, causing the wheel to revolve with the same number' of revolutions in a given time irrespective of the load placed thereon, since immediatelyy when the load is varied the governing-weight E is instantly operated to shut off or put on the steam, as desired. The weight being arranged upon a guide requires less strength of spring to retract the same. This arises from the fact that the spring does not have to stand the entire centrifugal force of the Weight E. It will be understood -that the tendency of the weight E is in an ever-increasing peripheral curve, and this tendency forces the weight against its guide, causing the said guide to withstand a certain amount of the centrifugal force, which would otherwise come directly upon the spring. This produces an even movement of the weight E, prevents undue straining of the retracting-spring, and also causes the weight to remain at. its desired position Without variation until the load is varied. Moreover, in order to further increase the working-power of the spring the same is offset from the line of motion of the weight E.

In order to counterbalance the lug B2, I pro vide on the opposite side of the support B a like lug B3. Although this lug may be of any desirable form or construction, I prefer to provide the same with a pivot-point b2 at the same distance from the center of the eccentric support as the pivot-point of the opposite arm. By this means, when it is desired to run the engine in the opposite direction, the connection F is disconnected at the point f, and is then swung over on the pivot f until the pivot f is engaged with the opening b2 of the lug B3. t will thus be seen that the balance-wheel can be revolved in the opposite direction without changing 'the operation of the governor. This latter feature is one of great advantage, since frequently it is desirable to change the direction of revolution of an engine, whereupon the parts must be ordinarily altered to allow the reverse motion. However, when this improved governor is connected to an engine, the only operation or adjustment necessary is to disconnect the connection F from one point of attachment of the eccentric support, and then connect to the oppositely-arranged point of attachment of said support.

When the connection F is shifted to the position illustrated in Fig. 2, the spring G is connected on the opposite side of the arm B. In order to allow of this moving of the spring G, the eye g to which the same is attached, is preferablysecured to the balance-wheel by means of screw-threads, and on the opposite side of the arm B is a socket, with which said eye is engaged.

At Fig. 4L I have illustrated a modied construction of my governor. In this case the arm B3 is shortened, and is provided with a weight of suitable size and shape. The connection from the weight E to the arm B2 is also varied, and instead of a coil-spring I use a leaf-spring II, secured on the innerv periphery of the balance -wheel rim, and connected by a turn-buckle I to the connec-v tion F.

The operation of my invention will be readily perceived from the foregoing, and it will be understood that my governor consists of but few parts, and that the peculiar construction thereof renders the operation very quick and sensitive, and prevents undue strain upon the retracting-spring. It will be understood that considerable change may be made in the detail construction and arrange ment of the parts of my invention without departing from the spirit thereof; hence I do not limit myself to its precise form and con-` struction. y

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a governor, the combination of an oscillating eccentric-operator for changing the throw of the eccentric, a guide arranged diametrically opposite to the pivot-point of said support, a centrifugally operating weight guided by said guide, a connection between said eccentric operator and the Weight, and a spring for retracting said weight, substantially as described.

2. In a governor, the combination of arocking eccentricoperator B for changing the throw of the eccentric, a centrifugally-working Weight E, a guide-rod d for said weight, and the link F, hinged to the said eccentricoperator and weight E, and also to the spring for retracting the Weight, substantially as specified.

3. In a governor, the combination of anoscillating eccentric-operator for changing the throw of the eccentric, a guide arranged dia-v metrically opposite to the pivot-point of said support, a centrifugally operating weight guided by said guide, a link F, pivoted to the weight and pivoted o the center of the eccentric-operator, and a spring for retracting said weight, substantially as specified.

4. In a governor, the combination of an 'oscillating eccentric-operator for changing the throw of the eccentric, a guide arranged diametrically opposite to the said eccentric-operator, a Weight guided by said guide, connection-points on either side of the center of said eccentric-operator, a link connected to IOO IIO

seid Weight and adapted to be connected to either of said conneeton-points 0f the eccentrc-operator, and a spring for reti-acting said weight, substantially as described.

5. In a governor, the combination of an eccentric-operator, a. projecting arm provided from opposite sides of n connection F from the weight to either of Said arms B2 and B3, and the spring for retreating said Weight, 15

substantially as speeed.

In testimony whereof I have hereunto signed lny nan1e,in the presence of two ettestng Witnesses, at Syracuse, in the county of Onondaga, n the State of New' York, this 2o 10th day of July, 1889.
